Initial Set-up And Activation For First Use And After A Storage Period

Did you get perplexed after seeing so many parts and controls? If yes, I remind you that I am here to help you. It is essential to know every process of a coffee machine because it ensures that the Brewer is accurately assembled and ready to brew high-quality coffee.

So get ready to have another informational ride on your Keurig K-45, but this time we will explore its initial setup and activation.

Note: It is important to note that if your coffee Brewer has been exposed to freezing temperatures, it should be allowed to reach room temperature for at least two hours before attempting to use it for brewing. It is because a cold Brewer needs to be fixed and may result in malfunction or poor-quality coffee. Allowing the machine to reach room temperature before using it will ensure it can function properly and produce delicious coffee.

Important: You can only use your Brewer once it is set up according to the following instructions.

Setting Up Your Brewer

  1. Once the coffee Brewer has reached room temperature, it is time to set it up. The first step is to remove the wrapping from the cord and plug the machine into a grounded outlet. Then, unwrap the packing tape from the Brewer to ensure it is fully operational.
  1. To brew coffee, place a large mug (with a minimum capacity of 10 oz.) on the Drip Tray Plate of the machine.
  1. To remove the water reservoir from your Brewer, lift off the lid from the reservoir (as shown in figure 1). Next, gently lift the reservoir straight up and away from the Brewer. Be careful, as it may be a bit tight. Once you have removed the reservoir, give it a good rinse with fresh water to ensure it is clean and ready for use.
  1. Now, to brew the coffee, fill the water reservoir with bottled or filtered water, but make sure that it should not exceed the MAX FILL line.
  1.  Make sure the Water Reservoir Lock Tabs are engaged with the Brewer before inserting the Water Reservoir base into the left side of the Brewer (fig. 2). Now, replace the water reservoir’s lid.
  1. To turn on the Brewer, press the power button placed on the upper right panel, and the green power light will illuminate. 

Note: It should be kept in mind that a K- Cup should not be used for this sequence.

Note: If a blue light ADD WATER starts illuminating, the Water Reservoir is empty or not in place on the Brewer.

  1. The Brewer will automatically start filling the water and heating it up. This process will take about 4 minutes to complete. During the heating process, the red Heating Light will turn on. Once the water is heated, the red Heating Light will turn off, and the Small Cup, Small Mug, and Large Mug buttons will illuminate.

NOTE: Never lift the handle during this heating period, or it can burn you.

NOTE: Small amount of water may start coming from the vent and dripping into the Water Reservoir during this and another heating process. You should not worry about this because it usually happens during this process.

  1. Raise and lower the handle. Press the small mug button to initiate a cleaning cycle ( figure 3). Empty the hot water into the sink.
  1. After brewing, the machine may need a few seconds to reheat the water for the next brew. During this time, you may notice the red heating light turning on. Once the water reaches the correct temperature, the red light will turn off, indicating it’s ready for the next brew.
  1.  As the one- time-step- up is completed, you are ready to brew your first coffee.

Ready To Brew Your First Cup Of Coffee

  1. When the machine is turned on, you’ll see a green light indicating it’s receiving power and is ready to use.
  1. Place a cup or mug on the Drip tray plate
  1. Now, open the K- Cup holder. It will open towards you when you lift the handle, as shown in figure (Fig.4)
  1. Choose your favorite K-Cup Pack.

Note: Avoid puncturing the K-Cup or removing the foil cap.

  1. Insert a K-Cup into the designated holder, as illustrated in figure 5.

Note: You should be careful doing this part as there are two pointed needles to puncture the K-Cup, one located above the K-Cup Holder and the other at its bottom. Do not stick your fingers in the K-Cup Holder to reduce the risk of injury. 

  1. To start the process, close the lid by lowering the handle.
  1. Choose the size of the brew according to your mood. You have the option of a small cup, which will give you 5.25 ounces, a small mug, which will give you 7.25 ounces, or a large mug, which will give you 9.25 ounces.

Note: If you don’t start a brew within 60 seconds, the brew buttons will automatically deactivate to prevent accidents. To reactivate them, simply lift and lower the handle.

  1. The blue Brew Button you choose will remain illuminated while brewing.

Note: You should remain careful because the K-Cup will be very hot.

  1. Please be patient; there may be a slight delay before the brewing process starts. After about a minute, you will notice that all of the liquid from the K-Cup will be fully expelled through a burst of air.
  1. Now lift the handle, take out the used K-Cup, and throw it away.

Caution: The K-Cup is still hot; dispose of it carefully.

  1. You are now ready to savor your first cup of Keurig K-45 brewed coffee, tea, or hot chocolate.
  1. The red Heating Light will turn on as the water heats up for the upcoming brew cycle. It will take around 15 seconds for the Brewer to be ready to use.
  1. During the brewing process, the LED Control Center’s red light next to “HEATING” will turn on to indicate that the water is being heated for the next brew cycle. It is normal. In about 15 seconds, the Brewer will be ready for use again.

Note: There is no need to be alarmed if the pump starts vibrating after your brewing because this usually occurs when the Brewer starts filling in preparation for the next brew.

Stopping The Brew Process

If you want to stop brewing due to any interruption or urgency, rest assured that it is a simple task. With a single power button press, you can instantly shut down the heating process. You will witness that the flow of coffee or tea will immediately stop, and the green light will no longer flash. It allows you to attend to urgent matters without delay or hassle. You can always resume the brewing process later on. So you can enjoy your coffee or tea without any interruptions.

Note: You could get less coffee, tea, or hot chocolate in your cup with the next brew. After finishing a brew, I recommend you perform a water-based cleanse. Consequently, your NEXT brew will have the appropriate volume.

Adding Water

Do you know that your Keurig K-45 has a convenient feature that alerts you when it’s time to add water? The LED Control Center on your coffee maker will display a blue light next to “ADD WATER” when the water level in the water reservoir is low or if the reservoir has been removed. This blue “ADD WATER” light will prevent the Brewer from functioning until water is added, as shown in (Fig 6). This feature ensures that you always have enough water to brew your coffee, tea, or cocoa, making your brewing experience seamless.

How To Add Water In Your Brewer In Keurig K-45?

  1. First, Remove the lid, add water to the Water Reservoir while it is still connected to the Brewer, and then replace the lid. Never make the mistake of filling the water beyond the “MAX FILL” Line, as it will start overflowing.
  1. Before lifting the water reservoir from the Brewer, make sure first to remove the lid. Then lift the water reservoir and place it away from the Brewer. Then, fill it up with water. Once done, securely replace the lid and reattach the water reservoir to the Brewer. 

Caution: It is essential to remember that the water reservoir should never be removed while the brewing process is ongoing to avoid any accidents or interruptions.

Descale Your Brewer

Do you know that over a period of time, a mineral buildup can occur in your Brewer? This buildup, consequently, can negatively affect the performance and taste of the coffee as well as the lifespan of your Brewer. Hence, it is really important to descale your Brewer regularly. Following are some important tips I want to share with you.

  1. In order to maintain optimal performance, you should descale your Brewer every 3-6 months. However, if you use it frequently, then the calcium deposits build up at a faster rate, so it may be necessary to descale the machine more frequently.
  2. Flashing of the Red Descale light will indicate when your Brewer asks for a descale. However, if it doesn’t, I would still recommend you to descale it every 3-6 months.

How to Descale your Keurig K-45?

Note: Don’t insert a K-cup pod.  

  1. Repeat the brewing procedure until the blue Add Water Light flashes.
  2. Leave the Brewer for at least 4 hours while it is still turned on.

  1. Ensure the Water Reservoir is full of fresh water but not beyond the MAX FILL line.
  2. Place a big cup on the Drip Tray Plate and run a cleansing brew. Then, dump the contents of the big cup into the sink.
  3. Repeat the brewing procedure until the blue Add Water Light is turned on.
  4. Now, Even after following all the steps, you may need to do further cleansing brews if you notice any residual flavor.

Note:  If the red Descale Light remains on after finishing the operation, restart the descaling procedure described above.

How To Store Your Keurig K-45?

Sometimes you won’t be using your Brewer; it is important to store it to ensure it remains in good condition properly. By following the steps, you can ensure that your Brewer is always in good working condition and ready to brew your favorite coffee whenever you desire.

  1. To properly store your Brewer, empty the water reservoir and place it in a dry and secured location. It will help prevent any moisture damage and keep it safe while it is not in use.

Note: Please keep your Keurig K45 in its straight position to prevent water leakage from the inner tank.

  2. To store your Brewer, turn it off, empty the water reservoir, and let it reach room temperature for at least 2 hours if it was exposed to below-freezing temperature before moving.


You do not need to ruin your mood if your Brewer starts showing signs of a malfunction because You can fix those problems yourself. Moreover, it is also important to know how to troubleshoot and fix your Brewer because it can save you time and money.

Helpful Hints

Before I go, I want to share some helpful tips with you so you can have a great experience while using your Brewer.

1.   Keep Your Brewer Turned ‘ON’ At All Times

If you want to enjoy a fresh cup of coffee, tea, or hot cocoa whenever you want, I recommend keeping your Brewer turned on at all times. This way, you won’t have to wait for it to heat up. Alternatively, you can set your Brewer to automatically turn off after two hours of inactivity to save energy.

2.   Use Bottled Or Filtered Water.

If you want your coffee to taste better, I suggest using filtered or bottled water. Sometimes, the water from your tap may have a bad taste of chlorine or minerals. To avoid this, use filtered or bottled water instead. It will make your coffee taste much better.

Does The Keurig K-45 Have A Water Filter?

The Keurig K-45 is equipped with a water filter starter kit. The requirement for a water filter is determined by the quality of the water source you are using.

 Is It Ok To Use Keurig Without Filter?

While it is possible to use tap water or any other water source without a water filter on the Keurig machine, the purpose of the water filter starter kit is to eliminate any unpleasant taste or odor from the water used for brewing coffee. It is not a necessary functional component of the Brewer. Many users prefer to use filtered water from their fridges or purified bottled water for a better taste experience.

Can You Clean A Keurig With Just Dish Soap?

It is possible to use dish soap for cleaning the water reservoir of your machine, provided that you rinse it thoroughly to remove any soapy residue before putting it back into the machine.

Do I Need To Descale My Keurig If I Use Filtered Water?

The frequency of descaling is determined by the mineral composition of your water. This is why I recommend the use of filtered or bottled water. Calcium deposits or scale can accumulate in your Brewer and impair performance. Descaling your Brewer every 3 to 6 months can help avoid this from happening.
